Significant Changes

The date-time fields passed as API parameters or Params should be RFC3339-compliant (#29395)

In case of API calls, it was possible that "+" passed as part of the date-time fields were not URL-encoded, and
such date-time fields could pass validation. Such date-time parameters should now be URL-encoded (as %2B).

In case of parameters, we still allow IS8601-compliant date-time (so for example it is possible that
' ' was used instead of T separating date from time and no timezone was specified) but we raise
deprecation warning.

Default for [webserver] expose_hostname changed to False (#29547)

The default for [webserver] expose_hostname has been set to False, instead of True. This means administrators must opt-in to expose webserver hostnames to end users.
